I have the following issue on a Maven project (with Maven 3.8.1):

Compilation failure
error: error reading ${user.home}\my-repository\path\to\the\artifact\version\dependency-version.jar; error in opening zip file

I have found a lot of posts on the matter (such as Maven : error in opening zip file when running maven) but none with a reliable solution. The only workaround that helps is to manual download the JAR file from a browser and save it at the location mentioned in the error.

In my case, I would like to know if the fact that the repository is over HTTPS and using an internal Certificate Authority could be the cause since:

  • while investigating the issue, I saw warnings as follow:
[WARNING] Checksum validation failed, expected <!DOCTYPE but is 963eb274a2ab77544a448a617489e097a3797b81 from my-maven-repo for https://<host>:<port>/repository/my-maven-repo/path/to/the/artifact/version/dependency-version.pom

[WARNING] The POM for path.to.the:artifact:jar:version is invalid, transitive dependencies (if any) will not be available, enable debug logging for more details
  • then, when opening https://host:port/repository/my-maven-repo/path/to/the/artifact/version/dependency-version.pom into a browser, it returns an error as : NET::ERR_CERT_AUTHORITY_INVALID

If so, how can I solved it?

NOTE:

  • ${user.home} is the placeholder set in the setting.xml in the localRepository element, which refers to the .m2 directory under the current user directory.
  • the setting.xml is set at project-level into the .mvn directory, along with a maven.config file, and holds all repositories configurations.

The pom.xml section:

    <resources>

        <directory>src/main/resources</directory>
        <excludes>

    where did you add `${user.home}\my-repository\path\to\the\artifact\version\dependency-version.jar` ? Could you add more info: 1. your `pom.xml` 2. do you use some custom `settings.xml` for maven? – Rustam Dec 20 '22 at 16:00
  • @Rustam - Here are a few complementary information: 1) ${user.home} is the placeholder set in the setting.xml in the localRepository element, which refers to the .m2 directory under the current user directory. 2) the setting.xml is set at project-level into the .mvn directory along with a maven,config file. 3) I am not entitled to provide any of the pom.xml files (NDA stuff) – Ceddaerrix Dec 21 '22 at 09:20
  • got it, it is not necessary to provide all `pom.xml`, just which plugin is used inside your ``, do you use some repositories in ? Looks like there are lack of information in your setting.xml, and also looks like you have repositories tag in pom.xml with `https://host:port..`, however it should be some placeholder for `host` and `port`. You have to config setting.xml correctly: https://maven.apache.org/settings.html – Rustam Dec 21 '22 at 09:34
  • @Rustam - As mentioned in my latest edits, the repositories tag are in the `.mvn/settings.xml` (instead of the pom.xml) with `https://host:port/repository/my-repo/`. Searching here and there I am just wondering if I should add from SSL-related properties into the MAVEN_OPTS – Ceddaerrix Dec 23 '22 at 04:50
  • `https://host:port` is not correct, use necessary `host` and `port` – Rustam Dec 23 '22 at 08:58
